Down load Strelok on your phone and use it. You are able to set your zero and adjust the zoom on the optic. Depending on the range it will adjust for your scope.Though your zero at any range will be your zero.... guess I am not understanding what you are trying to accomplish? The extra 2x on your scope will really make no difference with the ranges we are shooting with airguns. Heck I shoot out to 1k yards on 10x quite regularity.
Ok I got ya... misunderstood you.Yeah just re do it. It shouldn't be that much off to be honest. Now if you were going from 10x to say 19x that would be a huge change. But from 10x to 12x it probably wouldn't be to much.
Well ya,. You moved ,changed , unmounted . Pretty much a fresh start over. (Opinion).
Does the extra 2x power even make a difference in your opinion?
